Top 10 Best 5G Network Providers In Singapore 2026

Singapore's 5G market has matured fast. What began as a two-horse race between Singtel and StarHub now includes four fully licensed mobile network operators and a crowded field of sub-brands and MVNOs fighting for the same SIM slots. For consumers, that competition has pushed prices down and data allowances up, but it has also made the choice harder. The best 5G network provider in Singapore for 2026 depends on whether you prioritize raw speed, indoor coverage, roaming bundles, or the lowest possible monthly bill.

We built this ranking from independent benchmark data, published plan pricing, and network architecture, not marketing copy. The 2026 nPerf Barometer and the latest Opensignal reports anchor the performance side, while operator disclosures and current plan sheets cover pricing and coverage claims.

How We Ranked These

Our evaluation weighed four factors: independent network performance scores from nPerf and Opensignal, 5G coverage and availability data, plan value measured in data per dollar, and network ownership. Operators running their own licensed infrastructure got an edge over resellers because they control their own rollout and capacity. We also factored roaming allowances and customer support access, since those matter to frequent travelers and less technical users. Pricing reflects published rates as of early 2026 and excludes short-term promotional discounts except where noted.

The Top 10 Best 5G Network Providers In Singapore 2026:

1. Singtel

Singtel ranks first in Singapore according to the 2026 nPerf Barometer, taking the highest overall score in mobile network performance and leading across key indicators. The carrier posted a median 5G standalone download speed of 462 Mbps, roughly 1.7 times the 269.51 Mbps global standalone median, and recorded an average network speed of 182.5 Mbps.

Opensignal data reinforces the picture. Singtel leads in 5G upload speed, 5G availability, 5G games experience, and reliability experience, meaning its customers spend more time connected to 5G than users on any rival network. The company markets its 5G+ network as Singapore's fastest and widest, and the independent numbers largely back that claim.

For anyone who wants the network that wins the most benchmarks, this is the straightforward answer. The trade-off is price. Singtel's own-brand plans sit at the premium end of the market, which is why its sub-brands GOMO and the MVNOs riding its network appear further down this list.

2. M1

M1 holds the fastest 5G download speeds in Singapore per Opensignal, edging out StarHub and Singtel in that specific metric. It shares joint winner status in 5G video experience alongside both competitors, and it offers nationwide 5G coverage with performance that matches the leaders above ground.

Where M1 gives up ground is indoor edge cases, where signal penetration in older buildings and dense structures can lag slightly behind Singtel and StarHub. In practice, most users won't notice the difference outside of specific dead zones.

On price, M1 undercuts Singtel meaningfully. Its cheapest 5G SIM-only plan delivers 150GB for S$14.95, which is aggressive for a full MNO with its own spectrum and infrastructure. M1 also owns the Maxx sub-brand, covered below, giving budget-conscious buyers a second route onto the same network.

3. StarHub

StarHub claims over 99% 5G coverage across Singapore and deployed nationwide 5G early alongside Singtel. It ranks second in 5G availability per Opensignal, meaning its customers spend the second-most time on 5G, and it shares joint winner honors in 5G video experience with M1 and Singtel.

The carrier's standout strength is indoor coverage. StarHub performs best in MRT tunnels and shopping mall basements, areas where signal quality separates a usable network from a frustrating one during peak commuting hours. That matters more in Singapore than raw speed figures suggest, given how much daily activity happens underground.

StarHub's Star Plan L costs $32 per month for 200GB with 5GB of data roaming across five destinations. The company also owns giga! and eight, two sub-brands that extend its reach into the budget tier.

4. SIMBA (TPG Singapore)

SIMBA is the consumer brand of TPG Singapore, the fourth fully licensed mobile network operator, licensed in 2016. Unlike MVNOs, it holds its own 4G and 5G spectrum and runs its own network rather than reselling capacity from an incumbent. That independence is rare in this market and gives it long-term control over its rollout.

Opensignal scored SIMBA 8.9 out of 10 for 5G Coverage Experience, and it ranks second in reliability experience behind Singtel. The weak spot is 5G availability, estimated at just 31.4%, meaning users spend far less time on 5G than customers of the three incumbents. Its build-out is also the newest of the four MNOs, so indoor coverage in older buildings can still lag.

Pricing is where SIMBA overwhelms the competition. Its entry plan starts at S$5 for 500GB of local data, 5GB APAC, 3GB global, and 400 SG/IDD minutes. The 500GB plan runs S$10. No other licensed operator in Singapore comes close to that data-per-dollar ratio.

5. Circles.Life

Circles.Life is the only MVNO in our top tier, riding on M1's network, which means its coverage is identical to M1's down to the last cell site. It compensates for the lack of owned infrastructure with the most aggressive data pricing in the market.

Its 5G plans start at 200GB for $12 and scale through 300GB, 600GB, and up to 2TB tiers. The Circles Plus plan at $18 per month ($10.99 for the first month) bundles 300GB with 8GB of monthly roaming across seven countries, plus a free AI bundle powered by OpenAI GPT-5 and Perplexity Pro. That AI inclusion is unusual among Singapore telcos and reflects the company's push to differentiate on software rather than spectrum.

For most users who want a large data allowance without paying MNO prices, Circles.Life is the benchmark against which other MVNOs get measured.

6. GOMO

GOMO is Singtel's app-only sub-brand, running on Singtel's own network rather than reselling capacity. That distinction matters: GOMO customers inherit the fastest network speeds in Singapore, as confirmed by nPerf's 2026 ranking.

The 5G+ Value plan costs $19.99 per month, with a $10.00 promotional rate for the first three months. It includes 400GB of local data plus 400GB APAC roaming, 28GB across Asia, and 10GB worldwide roaming. That roaming stack is among the most generous on any Singtel-network plan.

GOMO also offers a 5G+ Senior plan and a 5G+ Core tier, giving the brand coverage across different user profiles. For travelers who want premium network performance without premium pricing, it's the strongest roaming-first option on Singtel's infrastructure.

7. Maxx

Maxx is M1's value-focused brand, delivering M1-level coverage at prices that undercut the parent company's own plans. Its True 5G plan costs $12 per month for 600GB usable across ten countries: Singapore, Malaysia, Indonesia, Hong Kong, Thailand, China, Bangladesh, and India, alongside 20GB of APAC roaming across 20 destinations and 7GB worldwide roaming across more than 100 destinations.

The plan also includes unlimited voice roaming, 500 minutes, 50 SMS, and 600 IDD minutes. Its base plan starts at S$7.90 per month for 290GB for the first twelve billing cycles, rising to S$9.90 after.

The cross-border data allowance is the headline. Few plans at this price point let you use your local data bucket in eight or more countries, which makes Maxx a practical pick for frequent travelers to Malaysia, Indonesia, and Thailand.

8. giga!

giga! is StarHub's app-only sub-brand, running on StarHub's own network and therefore benefiting from its strong indoor coverage and 99% nationwide reach. The gigaFLEX+ plan costs $9.90 per month for the first three months, then $19.90, for 800GB of data usable in Singapore, Malaysia, Indonesia, and Thailand.

The plan includes 22GB of monthly roaming and rollover data, with no age restriction. giga! also offers a 500GB Hot Deal plan and an age-gated plan giving 400GB at $11.90 for users aged 15 to 29.

One caveat worth flagging: across a full twelve months, gigaFLEX+ averages out more expensive than Maxx's comparable offering. The introductory pricing and rollover feature are genuinely useful, but long-term subscribers should run the math before committing.

9. Zero1

Zero1 is an MVNO on Singtel's network, offering access to Singapore's top-ranked infrastructure at a lower price than GOMO. Its Streamo Freedom plan costs $15 per month for 700GB of local data, 1TB yearly across Malaysia, Indonesia, and Thailand, 30GB of monthly Asia Pacific roaming across 13 destinations, and 60GB yearly worldwide roaming across 198 destinations.

The plan also includes 600 minutes, 100 SMS, and 500 IDD minutes. Roaming coverage at this breadth is rare below the $20 mark.

What separates Zero1 from most MVNOs is its physical service centre at Tai Seng. Face-to-face support is a genuine differentiator in a segment where most competitors operate app-only, and it matters to customers who want human help with SIM issues or billing disputes.

10. ZYM Mobile

ZYM Mobile is an MVNO on the Singtel network, and its Roam Smart (5G+) plan costs $15.10 per month for 700GB of local data, 1TB yearly in Malaysia, Indonesia, and Thailand, and 30GB of monthly Asia Pacific roaming. Like Zero1, it operates a physical service centre.

The port-in promotion is the standout. New customers switching from any non-Singtel operator get a $0 bill during the fourth to sixth month, plus a free eVoucher worth $190. Stacked against a $15.10 monthly rate, that's a meaningful effective discount in the first half-year.

One detail buyers need to catch: the Roam Plus 4G plan does not include 5G access. Anyone wanting 5G must select the 5G+ tier specifically. That plan-naming trap, combined with slightly higher pricing than Zero1 and SIMBA, is why ZYM lands tenth despite matching its peers on most other measures.

The best 5G network provider in Singapore for 2026 comes down to what you value. Singtel wins on every independent performance benchmark and remains the safest pick for coverage and speed. M1 and StarHub trade blows on download speed and indoor coverage respectively, and both undercut Singtel on price. SIMBA offers the cheapest entry point of any licensed operator at S$5, though its 31.4% 5G availability is a real limitation.

Below the MNO tier, the MVNO and sub-brand market is where most savings live. Circles.Life, GOMO, Maxx, giga!, Zero1, and ZYM Mobile all ride on incumbent networks at lower prices, and the differences between them come down to roaming allowances, promotional timing, and whether you want a physical service centre. For pure data volume per dollar, SIMBA and Maxx lead. For roaming-heavy users, GOMO and Zero1 stand out. For anyone who simply wants the fastest network in the country, Singtel remains the answer.
